Nope, they grow incredibly strong and large root systems
They actually grow into the gravel, so it gets this gravel platform that keeps it down at all times! Not to mention that I have about 4cm-7cm of gravel in the tank to keep the plants in place
The more gravel in the tank, the easier it is to keep the plants where they belong
I saw a plant called Onion plant, in one of my books, it's supposed to work really well in tanks with messy and destructive vegetarian fish
So I thought, why not goldfish? I'm just waiting for the shops to get some of them
They look just like onions!
